Special Focus

Advances in tieback cementing

Recent advancements employed in the Gulf of Mexico include delayed-gel cement slurries, tieback cement sheath modeling and reverse foam cementing.

External casing perforating pinpoints hard-to-reach pay treatment

How a new perforating system, plus other multi-zone stimulation advances improved well performance in West Texas.

Low-density propping agents improve hydraulic fracturing

As demonstrated in the Permian basin, a new proppant remains nearly buoyant in water-based frac fluids and assures more complete packing of created fractures.

Roadmaps improve extended reach well performance

Use of real-time mechanical and hydraulic modeling extends rig capabilities in modern, complex well environments, providing a drilling plan to follow.

Features

Evaluating petroleum systems in frontier areas using seabed geochemistry

When integrated with recognition of near-surface alteration, mixing and reworking, use of seabed geochemical data can reduce exploration risks.

Fluid weighting material yields low ECD, reduces sag

A chemical proven in other applications eliminates deposition in crude handling tubulars and flowlines. Several multi-well field examples show positive results.

Petroleum Technology Digest: Fracture mapping and modeling optimize CBM treatments

By using in-well tiltmeters and fracture modeling, an operator achieved per-well cost-savings of up to $50,000 at two coalbed methane fields.
